Event Processing
DataSplice 2.3.x
Event handling in DataSplice 2.3.x was performed by classifying the action under certain circumstances such as Before, After, or Instead Of.
DataSplice 3.0.x
Event handling is thoroughly expanded and revised in the 3.0.x version. Events can be placed in a chain that gets initiated by a specific action:
- Query
- Insert
- Update
- Delete
These chains can contain any number of events, which then occur in the defined order. In addition, several new event action types have been added:
- Error Action - Sends an error message to the client based on a particular condition.
- Check Filter Action - Requires that one or more fields are present in a query before it is executed against the target data source.
- Modify Filter Action - Appends filter items to the user specified query, which replaces the old Mandatory Criteria functionality.
- Modify Attributes Action - Adds/changes values in the attribute map before passing it on to the next action.
- Abort Chain Action - Aborts event processing and returns the current status (success or failure).
Also, the ability to send emails and call database procedures has been removed from the DataSplice Server and relocated in .NET plug-ins. Emails can be sent through Microsoft Exchange servers and well as with SMTP. For database procedures, the administrator no longer has to enter the procedure name; the list of available functions is automatically displayed.
In addition, actions are no longer explicitly marked as being Before, After, or Instead Of the underlying database action. There is a Default Action event type that can be part of the chain. This action can be placed anywhere in the chain, or deleted to have the same functionality as the old Instead Of actions.
Additional Information
For further information, see the corresponding event chain settings section of the DataSplice Administration Client manual.
